TX-SR603X 7.1-Channel Home Theater Receiver
 

Representing a new generation of Onkyo A/V receivers, the TX-SR603X brings you both stellar home theater performance and access to satellite radio through XM. Revolutionizing radio through innovative, commercial-free programming, XM Satellite Radio (sold separately) is best delivered through the precisely engineered, powerfully amplified TX-SR603X. With Powered Zone 2, you get the best of both worlds - engaging surround home theater in one room with a different , two-channel source (such as XM Satellite Radio programs, MP3s or Audio CDs) distributed to another. You can also take advantage of the onboard Auto Speaker Set-up with Microphone system to calibrate your speakers for the best possible sound from the listening position of your choice. Furthermore the TX-XS603X is easily integrated with all of your other components including the iPod through the optional DS-A1 thanks to the TX-SR603X's innovative Remote Interactive capability.
